Grammar question no. 83: would have

Perfect Strangerwhy did person B use would have done.

He is referring to a past impossibility. In the past (before he felt sick) he would have agreed, but now he cannot agree to the change of schedule.

CalifJimI believe that was addressed to Mr. M. so you need his input on this. However, I would say that we simply have to guess sometimes why a speaker has one thing or another in mind.
